This SAE Aerospace Standard (AS) specifies solid polytetrafluoroethylene (PTFE) retainers (backup rings) for use in static glands in accordance with AS5857. They are usually for use in hydraulic and pneumatic systems as anti-extrusion devices in conjunction with O-rings and other seals. NOTE: This specification includes material tests but does not include hydraulic or pneumatic performance tests. This document has been revised to: Add the requirement that no resizing of parts during the manufacturing process is permitted Clarify the use in AS5857 glands Add the stabilized temperature at which measurements shall be taken Add the dimensional stability requirement of material tubes to 4.1 Include some editorial corrections and improvements Update the references
